PCB layout and signal-integrity visualization for a 4-to-1 HDMI 2.0 mux
I wanted to test out Opus 5.5's ability to layout high speed signals, so I gave it the prompt to make 4 to 1 HDMI 2.0 Mux. Opus researched the chips, make the schematic and layout the PCB all in one shot. It took ~534K Output tokens, ~853K Input tokens, and took 2h 53m 5s. The high speed signals aren't too bad! But I would make some alterations and improvements if I were to actually build the board. The visualization still needs some work though!
